Track your power output the best way possible

There are multiple ways to measure your power output on the bike -- your hub, a computer, or even fitness apps on your phone. Each do a pretty good job at delivering reasonably accurate data, but none of them measure your output directly from the most logical point -- the pedals. Well, since its first 1989 Max One prototype, Look has been perfecting the technology of 'power pedals.' And after several years and just as many prototypes, the Look Keo Power Pedals have arrived as the lightweight and efficient alternative for power measurement.

The first of its kind, the Look Keo Power Pedals take the classic Keo design and equip it with an eight strain gauge spindle that measures the applied force and axle deflection. Sensors on both pedals collect data about your power and cadence, transferring them wirelessly from the crank arms to the Polar CPU with small P5 transmitters. Power output for your left and right pedals are displayed in percentages on the computer, along with your cadence and overall output numbers. That's right -- power readings for both legs. The entire system has an expressed accuracy of +/- 2%, and is compatible with the revolutionary Polar CS500, CS600, and CS600X computers. The exclusive pairing is both intentional and beneficial, as Polar played an integral role in the development of the Power Pedals. The joint development means that you can monitor your heart rate and power data wirelessly on the same computer with a heightened level of technicality. All of the gathered information lets you pinpoint exactly where your power is coming from, so that you can fully understand and dial in your training with Polar training programs like Polar ProTrainer5.

The Power Pedals use the same design as the Tour winning, and ever-popular, Keo Blade. With a lightweight composite body, mated to a stainless steel axle, the pedal body has a large contact surface for comfortable and efficient riding. The adjustable cleat retention lets you customize the tension of 10-18 nm, accommodating everyone from weekend criterium racers to the pro peloton. However, a few welcomed additions, like stainless steel platforms, have been made to the pedals for increased stability and power transfer.

Unlike most digital-era cycling technology, the Power Pedals refrain from an arduous, headache-inspiring installation process. Instead, they use a self-calibrating system that requires no time to program. This makes it simple to transfer the Power Pedals to every bike in your quiver. Simply, install the pedals and sensors, turn on the computer, and you're ready to ride. Battery life for each sensor is an ultra-long five months when used for three hours a day, every day. The Power Pedals and sensors weigh in around 405 grams without the CPU. So you can say goodbye to pushing around bulky rotational weight just to get your readings.

The Look Keo Power Pedals come with two P5 sensors and Grey Keo cleats. They're compatible with all colors of Keo cleats, and the Polar CPUs are sold separately.

Note: Manufacturer recommends professional installation by a qualified mechanic.
